considering the life and work of Jesus christ
We believe that in the fullness of time God sent forth His eternal Son as Jesus the Messiah, conceived by the Holy Spirit, born of the virgin Mary. We believe that, when the eternal Son became flesh, He took on a fully human nature, so that two whole, perfect, and distinct natures were inseparably joined together in one Person, without confusion or mixture. Thus the Person, Jesus Christ, was and is truly God and truly man, yet one Christ and the only Mediator between God and man. (John 1:1, John 1:14, John 5:18, John 8:24, John 8:58, Exodus 3:14, John 10:30-33, John 20:28, Col. 2:9, Phil. 2:5-8, Hebrews 1:8).
We believe that Jesus Christ lived without sin, though He endured the common infirmities and temptations of human life. He preached and taught with truth and authority unparalleled in human history. He worked miracles, demonstrating His divine right and power over all creation: dispatching demons, healing the sick, raising the dead, stilling the storm, walking on water, multiplying loaves, and foreknowing what would befall Him and His disciples, including the betrayal of Judas and the denial, restoration, and eventual martyrdom of Peter. (Psalm 2:7, 11-12, John 1:14, Luke 1:35, John 8:58, Isaiah 53, Matt. 1:21, John 1:29, 1 Peter 2:24, 1 Cor. 15:1-3, John 14:6, Acts 4:12, 1 Timothy 2:5, 2 Cor. 5:21, John 2:19, Luke 24:39, Romans 1:4, John 20:28-29, Phil. 2:6, John 5:23, Acts 10:25-26, Acts 14:14-15, Matt 4:10).
We believe that the Lord Jesus Christ, the eternal Son of God, became man without ceasing to be God, having been conceived by the Holy Spirit and born of the Virgin Mary in order that He might reveal God and redeem sinful man (John 1:1–2, 14; Luke 1:35). We believe that the Lord Jesus Christ accomplished ¬our redemption through His death on the cross as a representative, vicarious, substitutionary sacrifice, and that our justification is made sure by His literal, physical resurrection from the dead (Romans 3:24; 1 Peter 2:24; Ephesians 1:7; 1 Peter 1:3–5). We believe that the Lord Jesus Christ ascended into heaven and is now exalted at the right hand of God where, as our High Priest, He fulfills the ministry as Representative, Intercessor, and Advocate (Acts 1:9, 10; Hebrews 7:25; Hebrews 9:24; Romans 8:34; 1 John 2:1–2). We believe Jesus is coming again to judge the living and the dead (1 Peter 4:5; Romans 14:9; 2 Timothy 4:1).
Jesus had to be born as a human being for several reasons. One is outlined in Galatians 4:4–5: “But when the time had fully come, God sent his Son, born of a woman, born under law, to redeem those under law, that we might receive the full rights of sons.” Only a man could be “born under the law.” No animal or angelic being is “under the law.” Only humans are born under the law, and only a human being could redeem other human beings born under the same law. Born under the law of God, all humans are guilty of transgressing that law. Only a perfect human—Jesus Christ—could perfectly keep the law and perfectly fulfill the law, thereby redeeming us from that guilt. Jesus accomplished our redemption on the cross, exchanging our sin for His perfect righteousness (2 Corinthians 5:21).
Another reason Jesus had to be fully human is that God established the necessity of the shedding of blood for the remission of sins (Leviticus 17:11; Hebrews 9:22). The blood of animals, although acceptable on a temporary basis as a foreshadowing of the blood of the perfect God-Man, was insufficient for the permanent remission of sin because “it is impossible for the blood of bulls and goats to take away sins” (Hebrews 10:4). Jesus Christ, the perfect Lamb of God, sacrificed His human life and shed His human blood to cover the sins of all who would ever believe in Him. If He were not human, this would have been impossible.
Furthermore, the humanity of Jesus enables Him to relate to us in a way the angels or animals never can. “For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who has been tempted in every way, just as we are—yet was without sin” (Hebrews 4:15). Only a human could sympathize with our weaknesses and temptations. In His humanity, Jesus was subjected to all the same kinds of trials that we are, and He is, therefore, able to sympathize with us and to aid us. He was tempted; He was persecuted; He was poor; He was despised; He suffered physical pain; and He endured the sorrows of a lingering and most cruel death. Only a human being could experience these things, and only a human being could fully understand them through experience.
Finally, it was necessary for Jesus to come in the flesh because believing that truth is a prerequisite for salvation. Declaring that Jesus has come in the flesh is the mark of a spirit from God, while the Antichrist and all who follow him will deny it (1 John 4:2–3). Jesus has come in the flesh; He is able to sympathize with our human frailties; His human blood was shed for our sins; and He was fully God and fully Man. These are biblical truths that cannot be denied.
